NGINE ACCELERATOR.

Application filed May 29, 1824. Serial No. '716,705.

To aZZ whom it may cana-emt:

Be it known that I, CLYDE H. VINoEN-r, a citizen of the United States, residing at Oilton, in th County of Greek and State of Oklahoma, have invented certain new and useful Improvements in Engine Accelerators; and I do hereby declare the following to be a full, clear, and exact description ot the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to means whereby a motor of the internal combustion type provided for driving a vehicle may be accelerated either by foot or by hand as found most advantageous, the mechanism being such as to admit of acceleration of the en-.

gine by either the hand or the foot without one interfering with the other.

Other objects and advantages will be apparent and suggest themselves as the nature of the invention is understood.

While the drawing illustrates an embodiment of the invention it is to be understood that in adapting the same to meet difierent conditions and requirements, various changes in the form, proportion and ninor details of construction may be resorted to without departing from the spirit of the invention.

Beferring to the accompanying drawing it'orming a part of the application:

Figure 1 is a diagrammatic View in elevation, showing the application of the invention;

Figure 2 is a similar view in plan; and

Figure 3 is a detail sectional view on the line 3-3 of Figure 1.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawing by like reference characters.

The numeral 1 designates the foot board and 2 the dash of a motor vehicle and 3 designates the usual carburetor and i the throttle arin thereof. Associated with the carbureor is a shaft 5 from which arms 6 and 7 extend at an angle or" approximately 90 degrees. The arni 7 is connected to the arm 4: of the throttle and to the hand con trol not shown, and the arm (3 is connected with a pedal 8 mounted upon the foot board 1. y

Telescoping members 9 and 10 form connection means between the arm 7 and a rod 11 which is connected tothe hand control not shown. A longitudinal slot 12 formed in the member 9 receives a pin 13 carried by the member 10. A pivotal spring 14: mounted upon the member 10 is confined between a stop 15 and the inner end of the member 9 and normally tends to press the two members 9 andlO apart and hold the pin 13 at the outer end of the slot 12. A

pull upon the rod 11 efiects'a synchronous movement of the members 9 and 10 and the,

several arms 6, 7 and 4, whereby the engine is accelerated in a manner well understood Telescoping members 16 and 17 similar to the members 9 and 10 connect the arm 6 with a member 18 provided with the pedal 8. The member 17 has a' longitudinal slot 19 in which operates the pin 20 carried by the member 16 and this pin normally oc cupies a position at the outer end of the slot 19. The member 18 is pivotally mount` ed upon the foot board 1 and in the preterable construction consists of a rectangular frame one arm of which carries the pedal S and the otherarm having the member 16 pivotally connected thereto. A helical spring 21 connects the member 18 with the dash 2 and normally holds the pedal 8 in operative position to be depressed when the engine is required to be accelerated. WVhen the rod 11 'is pulled upon the engine is accelerated by hand and as hereinbefore stated both arms 6 and 7 move and when the memi ber 17 is connected directly to the arm 6 it v slides upon the member 16 without imparting any movement thereto( When the pedal 8 is depressed to accelerate the engine by foot, both members 16 and 17 move and the several arms 6, 7 and 4:, smultaneouslyj move and when the member 6 s connected directly to the arm 7 ,it slides relatively to the member '9 without imparting any movement thereto while at the same time compressing the spring 14 which subsequently reacts to return the parts to normal position. It will thus be understood that the engine may be accelerated either by hand or foot without one interfering with the other.

VVhat is claimed is Accelerating means for an internal combustion engine, the same comprising a fot-k having oppositely disposed arms, one of said arms having connection with the throttle arm of the carburetor, a telescoping connection having connection with one of the i arms of the fork and which the hand 'con- In testmony whereof I aflX my signature trols, and the other telescopng connection in presence of two witnesses.` being couplecl tothe other arm of the {ork ancl'ormng connectng means between it CLYDE VVINCENT; i v 5. and the foot control, and spring means for r Htnessesz normally mantanng the fork in a gven R.
